Offline delivery and self-running courses

1. Before opening a delivery

This recommendation applies to any executable file, not just P2LRN. The fact that a file has a P2LRN name or icon does not in itself prove who created it.

2. Delivery formats

For regular use in Windows, the EXE format is recommended. The CMD format remains as an alternative, not an “old” version.

3. Teacher → learner → teacher flow

4. Set up delivery in Studio

Open the course in P2LRN Studio and click Offline delivery. Before generating it, Studio requires that the course have Author and Rights holder in your authorship data and that you indicate Who delivers this course (teacher, center or organization). This data is displayed to the learner before startup is enabled.

You can configure:

5. What a self-running delivery records

In addition to the responses and scores generated by the course, the delivery may retain information about its use. The returned result may include:

• number of registered openings;
• date of first and last opening;
• logged session history;
• pseudonymous local identifier of the device;
• expiration date calculated from first opening;
• attempt made and duration;
• active time and course events;
• detected incidents, such as abnormal clock changes or use beyond established limits.

These data are incorporated into the .p2lrn-result so that the teacher can review them later.

6. Expiration and reuse

If the teacher establishes “Expires after first opening”, the period begins when the delivery is first opened. For example, with 30 days, a delivery opened on November 1st will be blocked on that computer after the 30 days are up.

Upon expiration, P2LRN blocks access on the device where it is registered. There is no physical deletion of the file as a security measure: deleting a copy does not delete other copies that may already exist.

Move the course and resume the same attempt on another device

Progress cannot travel inside a browser's local storage. To move it, take two files: the same offline delivery (.exe, .zip or extracted folder) and the progress .p2lrn-result. The signed course remains unchanged; the result is a portable sidecar. No internet access or database is required.

1. Device A: open the delivery with your individual learner code and work normally.
2. Before changing devices: select Save progress for another device. This creates an in_progress .p2lrn-result checkpoint with the current answers and events. Verify that your browser actually saved the file.
3. Transfer both: copy the same course EXE/ZIP and the progress file. Do not edit the course package or the JSON.
4. Device B: open the same delivery, choose Import progress and continue, select the checkpoint, then select Continue attempt.
5. When finished: select Finish and download result. The final .p2lrn-result retains the same learner and attempt identifiers with status submitted. Return this file to the teacher or import it into Analytics as the completed submission.

Import checks SHA-256, matching course/assignment version, learner code, attempt history and ordered records. It never silently overwrites local work. The feature is unavailable when the teacher disables resuming. Offline clocks and self-entered codes do not authenticate identity; expiry policies still apply. Analytics may show an in_progress checkpoint as pending, but it is not a final submission or grade. After transferring an attempt, continue only on the destination device: two independently edited copies are not automatically merged. If you close a device without exporting updated progress, only your latest saved checkpoint can be transferred.

7. Result and P2LRN Analytics

Upon completion, the learner downloads a file .p2lrn-result. That file can be:

• Open directly in P2LRN Analytics using Open results to select one or multiple files.
• Open from Studio with Review delivery and, from that review, press Open in Analytics.

The learner must deliver the downloaded file to the teacher by USB, email or another authorized method: downloading never sends it automatically. The teacher may import several results without a database or host a protected static index for src. See the CDN and NPM guides.

Analytics transforms the return into a view of learner, course, attempt, activity, openings and sessions. Scores from an offline submission are displayed as informational; They do not automatically become an official grade in an LMS or other academic system.

8. Review a return in Studio

1. Open the original course.
2. Click Review delivery and select the .p2lrn-result.
3. If you kept a receipt from the teacher, select it to compare the assignment.
4. Review learner, attempt, openings, first and last opening, expiration, sessions, active time, responses, scores and incidents.
5. If you want to explore the activity in the full dashboard, tap Open in Analytics.

9. Assignment signature and provenance

Studio allows you to sign the conditions of the assignment and save a separate receipt for the teacher. This verification helps confirm that the return corresponds to the assignment that the teacher created.

It should not be confused with the identity of the learner or the origin of the executable that Windows receives. When faced with any executable file, the rule for the learner remains the same: open it only if you know who sent it to you and expected to receive it.

10. What works offline

11. If Windows displays a warning

Don't disable SmartScreen, antivirus, or other protections to open a file you don't recognize. First confirm with the teacher or center that the file name, delivery channel and course are as expected. On managed devices, follow facility policies or consult the person responsible for the device.
